Assignment Instructions
Introduction
If you were asked to draw the structure of an atom, what would you draw? Throughout history scientists have accepted five atomic models. Our perception of the atom has changed from the early Greek model because of clues or evidences that have been gathered through scientific experiments. As more evidence was gathered old models were discarded or improved upon. Your goal is to trace the atomic theory through history.
Task
You will use the sources provided to develop a briefing that outlines the key scientists and experiments associated with the development of modern atomic theory. The briefing should include the names of the scientists, a description of the accomplishments, pictures of experimental equipment or atomic models, and description.
Process
Read the entire WebQuest !
Begin your research by using your textbook and the links provided in the resource section of the webquest to complete a research data sheet for each of the following scientists, experiments, and atomic models:
Democritus
J.J. Thomson
Gold Foil Experiment
Cathode Ray Tube
Law of Definite Proportions
Plum Pudding Atomic Model
Bohr Planetary Model
Robert Millikan
James Chadwick
Erwin Schrodinger
Eugen Goldstein
Law of Conservation of Mass
Dalton's Atomic Theory
Rutherford Model
Quantum Mechanical Model
Antoine Lavoisier
Ernest Rutherford
Dmitri Mendeleev
Niels Bohr
Henry Moseley
John Dalton
Prepare a timeline:
It should include information from your research data sheets presented in chronological order and pictures to illustrate your information.
In 1-2 sentences tell the importance of the discovery that relates to the structure of the atom (some of these people did many types of research)
A timeline is in chronological order – earliest time to latest time. Because you are going to keep your comments to 1-2 sentences, a report will not be appropriate. If you would prefer to do a PowerPoint presentation movie maker presentation, please discuss with the teacher and get approval.
After completing your project you should be able to: 1) Demonstrate an understanding of the present model of the atom by identifying the parts of the atom, the subatomic particle charges, and the relative location of each particle. 2) Demonstrate your knowledge of the history of the atomic theory by constructing a chronological order of events.
